Resistor 10K Ohm 1/4 Watt

The MCP3002 is a 10-bit analog-to-digital converter (ADC) integrated circuit that provides fast and accurate conversion of analog signals to digital form. It has two analog input channels, a single power supply voltage range of 2.7V to 5.5V, and a hardware-based sample-and-hold circuit for accurate signal capture. It operates using a successive approximation register (SAR) architecture, which provides fast conversion times and low power consumption, and features a built-in reference voltage generator. The MCP3002 communicates with a microcontroller or other digital device through a serial interface, such as SPI or I2C, and is available in a compact 8-pin PDIP or SOIC package.

The Universal IR Infrared Receiver TL1838 (also known as VS1838B or 1838) is an electronic component that receives infrared signals and converts them into electrical signals for processing by a microcontroller or other device. It is commonly used in remote control applications.
